3D Printed Patch Helps Heal Damaged Hearts

Harvard scientists may have just found a way to repair a heart after it sustains damage during a heart attack: using a layer of heart cells that replicate the way that natural heart muscle beats.

Human hearts are susceptible to damage after major problems such as a heart attack. After the damage is done, it is often irreversible. Currently, the only option for many is an organ transplant, but with so many on the waiting list for organs, and the high chance of complications for those who do receive transplants, it’s not always a positive outcome.

Repairing the heart tissue is the best solution but scientists have been searching for years to find a way to effectively do this. Previous attempts have fallen through when it comes to the material since it is hard to match the heart tissue. Human hearts are almost like elastic, and all attempts at a patch were gelatin like – meaning the materials didn’t resemble the heart closely enough to work. … (Read more)
